You boys know what tropism is, it's what makes a plant grow toward the light. Everything aspires to the light. You don't have to chase down a fly to get rid of it - you just darken the room, leave a crack of light in a window, and out he goes. Works every time. We all have that instinct, that aspiration. Science can't dim that. All science can do is turn out the false lights so the true light can get us home.
